[RFC PATCH-v2 1/3] dt-bindings: i3c: snps: Add Altera SoCFPGA compatible

From: Adrian Ng Ho Yin <adrianhoyin.ng at altera.com>

Add the "altr,socfpga-dw-i3c-master" compatible string to the
Synopsys DesignWare I3C master binding. This allows SoCFPGA
platforms such as Agilex5 to use the generic DW I3C master
controller while applying any required platform-specific quirks.
